I am torn between these 2 for one of my boys. I cant find any info on top speed for the YFZ50. Do any of you have any experience or knowledge on either or both of these kids quads? I guess the Suzuki can do 15mph when you remove the limiter spacer on the CVT and Yamaha has a rev limiter you can change for more speed, but no top speed spec for the Yamaha to be found.
